Chapter 5 Function parameter

When synchronous motor and the load can not be disengaged, have to choose
synchronous self-learning with load, in this process motor running at speed of 10rpm.
Before synchronous motor parameters self-learning with load, correct motor type
and motor nameplate parameters b0.00 ~ b0.05 should be set. Synchronous motor
parameters self-learning with load, the drive can get the initial position angle of
synchronous motor, which is a necessary condition for the normal operation of
synchronous motor, so before completing synchronous motor installation initial use, it
must proceed parameters self-learning.

Synchronous motor parameters self-learning without load
If the motor and the load can be disengaged, it is recommended to choose
synchronous motor self-learning without load, so as to get better running performance
than synchronous motor self-learning with load.
In self-learning without load process, the drive finish self-learning with load firstly,
and then follow the acceleration time from F0.13 to F0.01, after a period of time,
according to the deceleration time F0.14 decelerate to stop and end the parameters self-
learning. Note that when proceeding identify operation, F0.01 value must be set as non-
zero.
Before synchronous motor parameters self-learning without load, not only need to
set motor type and nameplate parameters b0.00~b0.05, but also need to correctly set
encoder type b0.28
、
encoder pulse count b0.29
、
encoder number of pole-pairs b0.35.
Synchronous motor parameters self-learning without load, the drive can get b0.11
~ b0.14 motor parameters, meanwhile it can get parameters of encoder b0.30
、
b0.31,
b0.32
、
b0.33, meanwhile get vector control current loop PI parameters F5.12 ~ F5.15.
Note: Motor self-learning can be only performed under keyboard operation mode,
terminal operation and communication mode operation can not perform motor self-
learning.

PI9000 supports multiple encoder types, the different encoders need different PG card,
please correctly choose PG card. Synchronous motor can choose any of the 5 kinds of
encoder, asynchronous motors generally only choose ABZ incremental encoder and
rotational transformer.
PG card is installed, it is necessary to correctly set b0.28 according to the Actual
situation, otherwise the inverter may not play correctly.

In vector control with PG, we must correct the parameter, otherwise the motor will not
run properly
